Reduction of Cross-Section-Induced Errors of the BN-600 Hybrid Core NuclearParameters by Using BFS-62 Critical Experiment Data

摘要

The present paper provides evaluation results of predicted uncertainty onrnnuclear parameters of the BN-600 hybrid core, a feasible option for Russianrnsurplus weapons plutonium disposition. Covariance data for nuclear grouprnconstants, analysis errors, as well as experimental errors are considered tornpredict the uncertainties by applying the nuclear group constant adjustmentrnmethod. Analysis results of BFS-62 mockup together with other fastrnreactor core experiments are reflected in the evaluation.
